Vitamin D does not help children (if only use 400 IU of D3 or D2 or quarterly) – Cochrane

I looked at the report and found the reason for the conclusion - tucked back on page 43+ 4 trials were examined - with awful dosing * 402 IU Vitamin D3 * 400 IU vitamin D2 * 400 IU Vitamin D2 * Quarterly Vitamin D3 See also VitaminDWiki * Infant infection reduced by half with vitamin D supplementation – RCT May 2016 * Third study found that Infants needed 1600 IU of vitamin D – JAMA RCT May 2013 *     1600 IU is 4 times larger dose size than that considered by Cochrane * Acute Lower Respiratory Infections in Children - associated with low vitamin D – meta-analysis Dec 2014 * Several more Vitamin D analyses fail to consider dose size, duration, etc. – Dec 2013 *     This Cochrane report fails for all 9 reasons listed * Overview Vitamin D3 not D2 includes many reasons to never use Vitamin D2 * Take vitamin D3 daily, weekly, or bi-weekly NOT quarterly! * Quarterly vitamin D3 is too infrequent – it increases the occurrence of pneumonia – June 2012 * 100,000 IU of vitamin D every 90 days was not frequent enough to prevent Diarrhea – Sept 2013 * Vitamin D dosing every three months is not often enough – found again – Jan 2016
